DRIVING-BOX AND HUB-LINER FOR LOCOMOTIVES;

Specification of Letters Patent.

Patented 0ct.-19,1915.

Application filed February 27, 1915. Serial. No. 11,078.

The invention relates to a driving box and hub liner for locomotives, and is also adaptable for use on engine trucks or trailer trucks.

The primary object of the invention is the provision of a box and liner of this character wherein any lug play can be obviated resultant from the grinding of the same and also wherein a new liner can replace the old when the hub becomes worn.

Another object of the invention is the provision of a driving box and hub liner wherein the cellar can be packed with hard grease or a sponge for lubricating purposes, the liner being readily renewed in event of the wearing of the hub, the said liner being preferably made from iron, brass, steel, or babbitt, while the crown brass employed in the driving box prevents it from working down and the clamp on the top of the box from working up. 7

A further object of the invention is the provision of a driving box and hub liner which is of novel form and is assembled in a unique manner to enable quick and con venient repair resultant from wear of the lug causing lug play or resultant from the wearing of the hub.

A still further object of the invention is the provision of a driving box and hub liner of this characterwhich is simple in construction, reliable and efficient in use, strong, durable, and inexpensive in manufacture and installation.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereunto appended.

In the drawing: Figure 1 is a fragmentary side elevation of a truck frame and pedestal showing the driving box and liner constructed in accordance with the invention mounted therein. Fig. 2 is an enlarged vertical longitudinal sectional view through the driving box and liner. Fig. 3 is a vertibox hereinafter fully described. l

cal transverse sectional'view thereof. Fig. 4 1s a sectional view on the lined- 1 of Fig. 1.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates a portion ofthe locomotive truck, and B the pedestal for receiving the driving The driving box 5 is of theordinary well-' known construction having the channeled sldes and top for the fitting thereof in the frame A, the pedestal B lying within the side channels in the said box, andv within this box is removably. fitted the cellar 6 which receives hard grease or a sponge for lubricating the hub of the driving axle. Fitted within the driving box is the crown brass 7 which is of theordinary well-known construction.

Formed in the outer face of the driving box 5 is adove-tail shaped guideway 8 in which is slidably fitted a removable liner 9, preferably made from iron, brass, steel, or babbitt, and is formed with a slot 10 to pro vide a clearance for the brass 7, on the driving axle, and the cellar 6 fitted within the driving box, the liner 9 being correspondingly shaped to the shape of the guideway 8 for sliding engagement therein to permit its free insertion and removal to and from the driving box.

{KNEE ea ers ra rnn'r carton.

When the'liner 9 is positioned within the results in play, the liner 9 can be removed for the replacing of a new one, thereby taking up wear and such play, or if desired, a new hub can be substituted.

The particular shape of the guideway 8 for the liner 9, and also the corresponding shape of the latter with respect to the said guideway, prevents the working out of the liner 9 from the said guideway, and also avoids displacement, as the said liner 9 is prevented from working downwardly by-its contact with the brass 7 and also the working upwardly of the said liner by the clamp at the top of the driving box. The clamp is in the form of a plate 11 which is fastened in securing position through the medium of a bolt 12 which is passed therethrough and secured in the driving box 5 at one side of the channel. in the top thereof for the fitting of the frame thereto. This plate 11 overlies the'upper end of the hub liner 9 to prevent the accidentalworking loose thereof. 7

From the foregoing description, taken in connection with the accompanying drawing, the construction and manner of use of the device will be clearly understood, and therefore a more extended explanation has been omitted.

l/Vhat is claimed is 1. In a driving box, a liner inset within the outer face of the driving box and removable therefrom, a brass within the driving box for preventing the working downwardly of the liner, and a clamp on the driving box to prevent the working upwardly of the said liner.

2. In a driving box having a guideway in its outer face, a liner correspondingly shaped to the guideway and slidable therein for permitting the insertion and removal thereof, a crown brass within the driving box to prevent the downward movement of the liner, and a clamp carried by the driving to box for preventing upward movement of the liner.

In testimonywhereof I affix my signature in presence of two witnesses.
